METHODS AND SYSTEMS FOR PRODUCING HIGH PURITY GASEOUS CHLORINE DIOXIDE

摘要

Methods and systems for producing high purity gaseous chlorine dioxide are provided. A solid chlorite reactant is contacted with an ozone-containing reactant gas, or a gas containing both ozone and a component that reacts with any hydroxide byproduct (such as carbon dioxide), to produce chlorine dioxide. The reaction can be monitored and controlled to ensure that excess chlorite reactant is provided and to prevent ozone from passing into the product gas.
